Greer caps Washington's truce offer at six months past November 10
The New York meeting on September 20 produced no deliverables, and the US trade representative says he would extend the 20% tariff cap by three to six months. The next deadline would land in spring 2027.

What happened
- Jamieson Greer told Bloomberg Television on September 21 that Washington is open to extending the tariff ceasefire by three to six months, while cautioning against expecting a quick resolution.
- The truce, assembled from agreements struck between 2025 and 2026, caps tariffs from both sides at roughly 20%, and it runs out on November 10, 2026.
- Scott Bessent, Greer and Vice Premier He Lifeng met in New York on September 20 to prepare the September 24 Trump-Xi summit, and US officials called the talks productive with no major deliverables.
- Critical minerals are the biggest unresolved issue, with Greer faulting Beijing's compliance on the rare earths and other strategic materials it committed to deliver.

Why it matters
- decision Importers now choose between pricing duty at the cap past next spring and hedging for reversion, because the best outcome on offer puts the same argument on a later date.
- cost Should the date pass unextended, rates go back up and the bill falls on firms that contracted on the assumption the cap would hold.
- constraint Greer's objection is about performance under a commitment that already exists, so a longer truce on rates leaves rare-earth buyers where they are.
- exposure Boeing's prospective order sits inside a deal that has not closed, and Airbus is working the same Chinese carriers while the deadline runs.
Greer spoke on September 21 and the cap lapses on November 10, which leaves 50 days [17]. Push the expiry out by three to six months and the next deadline sits between February 10 and May 10, 2027 [18]. A buyer signing twelve-month terms this week is quoting duty for a period longer than the tariff schedule underneath it.
An extension holds the roughly 20% ceiling that came out of the 2025-2026 agreements [4][3]. Sitting on top of it is the reciprocal cut still under discussion, covering roughly $30 billion of non-sensitive goods [8]. Cryptobriefing does not say whether the $30 billion counts one side's exports or both [20]. At 20%, that tranche carries about $6 billion of duty a year [19].
China committed to delivering rare-earth elements and other strategically important materials, and Greer said Beijing's compliance is "not up to par" [9]. Cryptobriefing writes that the semiconductor supply chain, already strained by export controls and reshoring, would face additional pressure if rare-earth supplies tighten further [16].
On the purchase side, the reported commitments run to 25 million metric tons of US soybeans a year and more than 200 Boeing planes [10][11]. Those are expectations of what Beijing would buy, and none of them is a signed order. Cryptobriefing describes an order of that size from Chinese carriers as a significant boost to Boeing's backlog, and says Airbus has been courting Chinese airlines aggressively [12][13].
The summit on September 24 could produce a framework that retires the deadline [5]. Or the two sides could land the three-to-six-month extension Greer described [1]. Or November 10 could pass and rates revert upward [14]. I would expect the extension, largely because the only number either government has put in public is a six-month ceiling volunteered by the side that wants the deal dated [1]. Rare-earth licence volumes arriving before November in quantities Greer would concede are up to par would change my mind, and so would a summit communique that removes the November date instead of moving it. Greer emphasised that both sides want to keep talking [15].
What to watch
- Whether anything out of the September 24 Trump-Xi summit removes the November 10 date.
- Rare-earth licence volumes leaving China before November, which is the test Greer set when he called compliance not up to par.
- Whether the reported order for more than 200 Boeing planes is signed, or whether Airbus takes those Chinese carriers.
